I tuned off journaling in UFS and removed the journal from the
partition. Although gjournal told me that the existing filesystem will
be destroyed this didn't happen since I did the newfs on the .journal
That's what I meant as "safe". In theory it was clear that I can safely
relabel the partition, but I was not sure if I understood everything
So far I have not had any problems with ahci, works great! (ich9)
At least with HDs, haven't tested ODDs yet. (I'm having burning problems
for a long time so I'm not used to use ODDs with FreeBSD)
One thing I'm missing is the possibility to spin down the drive.
I have my system on a SSD, the HD is just for ports nad stuff which
usually I don't make use of.
Is that planned to be integrated?
Another question is why "camcontrol tur ada0" returns "Unit is not ready"
readcap also doesn't work.
My SSD reports write and read cache present, but disabled. Is the report
or the status bad?
